Precision CNC Machined Components for IVD Instruments & Analyzers
Metal and engineering plastic parts for the fluid, optical, motion, and structural systems inside diagnostic equipment.
Discuss an IVD component →Component-level manufacturing
Support for the systems inside the instrument.
Kangsenlong’s component machining experience covers blood analysis, clinical chemistry, coagulation, urine analysis, chemiluminescence and point-of-care testing (POCT) equipment. Related applications include life science automation and analytical instruments.
We manufacture custom components to agreed drawings and specifications. We do not present the machining service as certification of a finished diagnostic device or as proof of its clinical performance.
For an effective review, explain how the part connects to the surrounding assembly. Interfaces, alignment points, liquid-contact areas, and inspection priorities help define the machining and quality approach.
Application focus
Custom Diagnostic Instrument Component Categories
Optical structures
Transparent components and optical supports. Identify observation areas, alignment features, and relevant surface requirements.
Motion systems
Transmission and mechanical components for instrument assemblies. Define fits, mating geometry, and assembly constraints.
Structural parts
Brackets, mounting surfaces, threaded features, and connection parts in metals or engineering plastics.
A practical handover from engineering to machining.
Start with the latest drawing revision, 3D model, material specification, and quantities. Separate mandatory requirements from features that may be discussed during engineering review.
Our machining scope includes CNC milling, turning, and 4-axis and 5-axis work. Inspection equipment includes CMM, vision measurement, electronic height measurement, and hardness testing; the methods used for your part are chosen to match the agreed requirements.
- Identify datum references and dimensions controlling instrument assembly.
- Specify material grade and documentation requirements.
- State surface, cleanliness, packaging, and handling requirements.
- Agree sample acceptance and inspection reporting before repeat orders.
Any device-level validation, regulatory documentation, or specialized testing must be discussed explicitly. These requirements are not implied by the term “medical component.”
Precision Manufacturing for Fluid-Path, IVD, and Analytical Assemblies
In hematology analyzers, clinical chemistry systems, liquid chromatography, and mass spectrometry, a single microscopic burr or out-of-spec sealing counterbore can cause carryover contamination, pressure drops, or reagent leaks.
Critical Features We Machine Daily
- Multi-Port Fluidic Manifolds & Valve Blocks: Precision intersecting micro-channels (Ø 0.3 mm to Ø 5.0 mm) with zero dead-volume geometries and leak-free plug/fitting interfaces.
- Flat-Bottom Ports & Precision Threading: 1/4"-28 UNF, M6, and 10-32 coned or flat-bottom chromatographic fluid ports with concentric sealing counterbores and controlled surface roughness (Ra 0.2–0.4 μm).
- IVD Motion & Sampling Mechanics: High-repeatability probe arms, syringe pump frames, optical cuvette holders, thermal cycler blocks, and light-tight optical housings (black anodized aluminum or carbon-filled PEEK).
Questions before you request a quote.
Which IVD applications do you support?
Our component experience covers blood, chemistry, coagulation, urine, chemiluminescence and POCT equipment. Send your drawing and component specification for project review.
Can you machine both plastic and metal instrument parts?
Our scope includes stainless steel, aluminum, copper, tool steel, high-temperature alloys, and engineering plastics such as PEEK, POM, PVDF, PTFE, PPS, PP, and acrylic. Exact grades are reviewed for the order.
What should I send for a quotation?
A dimensioned drawing, 3D model if available, material grade, quantity, critical interfaces, inspection needs, and application context. Include any customer validation or documentation requirements.
